PARCEL-POST CONTAINER.

Apliiication ined June 14..

To all whom it may concern Be it known that I, HERBERT BLANDFORD, acitizen of the United States,'residing at Elmira, in the county ofChemung and State of New York, have invented certain new and usefulImprovements in Parcel-Post Containers; and I do hereby declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart'of this specification. rlhe object of this invention isto provide anovel construction of foldable or collapsible box, constructed of somesuitable flexible material, such as paper, preferably cardboard, andadapted particularly for use as a parcel post mailing box to transportInerchandise, such as eggs.

More specifically, the object is to provide a box of this characterwhich does not require the use of paste, mucilage, or the like, toretain it in closed or sealed position, and which does not require anyfastening means,

such as paper fasteners, cords, or thelike,l

to maintain it in closed position.

A further object is to provide such a box which shall be exceedinglysimple lin com struction and which may be folded from a collapsibleposition to an operative position for mailing by the exerciseof aminimum number of steps.

The invention .is clearly disclosed in an exemplary form` in theaccompanying drawings, in which like` reference characters designatecorresponding parts throughout the several views. Brieiy described: Y s

which iiller is adapted to hold the eggs, or the like, in spacedrelationship.

Referring now in detail to the drawings, and first to Fig. 1 thereof,which shows the blank before being folded into the position shown inFig. 6, it will be seen that this blank is bent longitudinally along thedotted lines l and 2, extending from side to side of the blank. Theblank is slit along straight lines 3 and 4, parallel with the sides ofthe blank, said slits 3 and 4 running from and connecting the lines 1and 2. The area comprised between the lines 1, 2, 3 and 4 forms therectangular bottom 5 of the box. At a vpoint intermediate of the lengthof each of the slits 3 and 4, the bottom 5 of the liox is cut awaysegmentally, as shown at Intersecting the cut-away portions 6, 6 areslits 7, 7, which, as shown, extend from the sides of the'blank to saidcut-away portions, and parallel with the lines l and 2.

On each side of the slits 7, 7 the two sides of the blank are slit for ashort distance, as

- shown at 8, 8, parallel with the slit 7.

The blank is additionally creased, or folded, along the dotted lines 9,9, parallel with the lines 1 and 2, said lines 9, 9 being of a lengthwhich is equal to the distance between the slits 3 and 4, said lines 9,9 being at points in the plane of the slits3 and 4. From the end of saidlines 9, 9, the blank is slit, as shown at 10 10, extendin to the sidesof the blank. ach side of t'e blank midway between the slit 10 and thedotted linepl is slit for a short distance, as shown at 11.

rlhe blank is also folded along the 4dotted lines 12, 12, intersectingthe lines 9, 9 at the ends thereof, and runnlng from the ends of theslits 3 and 4 to the ends of the blank, as shown. The blank is creased,or folded, along the lines 13, 13, parallel with the lines 12, 12, andextending from two of the slits 10, 10 to one ofthe end edges of theblank, said lines 13,13 intersecting the slits 10, 10 at a pointintermediate the length thereof.

The larger area 14 bounded by one of the lines 9, the intersecting'lines 12, 12 and the edge 15 of the blank, constitutes the top of thelbox when the blank is folded, as shown in Fig. 6. I

The areas of the blank bounded by the dotted lines 9, 12, 12, and 1, andthe lines 2, 9, and 12, 12 constitute the side walls Q Levaeee 16, 16 ofthe box when the same is folded into the position shown in Fig. 6.

In folding up the blank from the position shown in Fig. 1 to theultimate position shown in Fig. 6, the side walls 16, 16 are bent up andthe flaps 17, 17 are turned inward so as to bear against the innersurface of the bottom 5 of the box, as shown in Fig. 2. The extensions18, 18 of said flaps 17, 17, constitute the e'nd walls of the box, asshown in Fig. 2. In this position the tongues 19, 19, formed by theslits 8, 8, are overlapped, so as to make an interlocking connection forthe flaps 17, 17, which rest upon the bottom 5 of the box. Also thetongues 20, 2O formed by the slits 11, 11, are overlapped, thus formingan interlocking connection between the two sections of each of the endwalls 18 of the box. rI`he Hap 21, forming the extension of the sidewall 16 is then folded in to underlie the top 14 of the box, as shown inFig. 6. The end tabs 22, 22 of said fiap 21, depend from the flap 21, asshown in Fig. 6, thus bearing against the end Walls 18 of the box. Thedepending side portions, or flaps, 23, 23 of the top wall 14 of the boxbear against the outer surface of the end walls 18 and extensions 24, 24of said flaps are folded inward between the iaps 17, 17 and the bottom 5of the box, as shown in Fig. 4:.

A suitable filler, or egg separator, may be disposed Within the box,and, While such a filler may take various forms, I show in the drawingsmy preferred form, which comprises two strips of suitable material, suchas cardboard, 25, 25 bent and folded along longitudinal lines 26 to formsuccessive connected transversely V-shaped portions, as shown. Thesetl-shaped, or arched, portions are provided along the topsl of thearches with a series of cut-away portions 27, for the eggs.

"What I claim to be new is:

1. A foldable box, formed from a single sheet of material and comprisinga top, a bottom, two side walls, and two end walls, said end walls beingcarried by said side walls, and each of said end walls being formed intwo sections, provided with overlapping interlocking tongues, and extenisions, carried by said end walls and disposed upon the inner surface ofthe bottom of said box and being provided with overlapping interlockingtongues.

2. A foldable blank box formed from( a single sheet of material andcomprising a top and bottom, two side walls, and two end walls, each ofsaid end walls comprising two sections, provided with overlapping,interlocking tongues, angled extensions carried by the bottom of saidend walls, and resting upon the top of the bottom of said box, andprovided with overlapping, interlocking tongues, and end flaps carriedby said top and comprising each a portion bearing against the exteriorof the adjacent end wall, and a portion extending between the box bottomand said extensions of the end walls.

In testimony whereof I hereunto aiiix my signature;

HERBERT BLANDFORD.
